I always hate it when someone blathers on this forum and does not answer the posters question. However, I'm going to do it now.
My brother-in-law,A good 5.8 GHz remote base phone should be fine in almost all homes. Make sure it's 5.8 GHz both directions. Some call themselves 5.8 GHz but are only 5.8 GHz one way and 2.4 GHz the other. Also you'll reduce the chances of your phone interfering with other things if you stay away from the 2.4 GHz band. Buy it from a store that will let you return it.
purchased a cordless phone with a remote base and all he did was complain about how much interference the phone had....
Utilizing the newly ratified DECT 6.0 frequency band, this phone provides the clearest voice reception available and can easily be used with Wireless Home Networking (WLAN) systems without negative impact. This phone offers state-of-the-art technology that provides brilliant sound and maximum voice security without interference from other wireless devices.
...Remember the 900Mhz?...I remember the ones before 900MHz! One of the advantages of the higher frequencies is a shorter antenna. The phones prior to 900MHz had long antenna that had to be extended. You could almost sword fight with them. Watch an old movie sometime.
Thanks for the help,
after contacting the BBB, my builder decided to install an actual phone jack in the location, which my wife wanted. It was in our contract, and we paid for it. Unfortunatly, now she wants a phone jack in every room of the house. My in-laws had a cordless phone with remote bases and all they complained about was the bad signal, I do not see how a phone system using the powerlines to move phone jacks, does not interfere with x-10 signals, since they both use the powerlines in the house to transmit signals.
It might actually be cheaper in the long run, not to mention a lot less frustraiting to bite-the-bullet and have the phone jacks hardwired. If you get the right guy to do it, it probably wouldn't cost too much more to have them run some CAT 5e or CAT 6 cables and jacks for LAN connections, TV cable, etc. while he is at it.
Not only does fishing wires provide hours of entertainment for yourself... you might be amazed at how many friends and neighbors will enjoy watching you fish wires for them too. And putting that phone jack, speaker, cable or ethernet connection, or receptacle, EXACTLY where the little lady wants it... really improves the WAF (Wife Approval Factor) the first time. Soon the wife will find MANY exact spots where an above mentioned connection should be located.
Think of the pride you will feel as the MILES of various wires are strung, stapled, and ran through conduit. Wiring isn't just a craft or a profession.... it's a fulfilling hobby! Soon you may find yourself as comfortable crawling through spider webs under your home .... as you are now, on your sofa. Or you may find the dry warmth of a 100 degree attic, as relaxing as a sauna.
